Abstract
提供用于滤色片的施主膜。所述施主膜包括支撑层、吸光层和转移层，其中所述转移层包括作为粘合树脂的由式(1)(见说明书)代表的丙烯酸树脂。根据使用本发明的施主膜生产滤色片的过程，每种颜色只要求转移和固化过程，如需要，也可以同时固化各颜色层，因此大大减少工艺步骤。从而容易生产使用所述施主膜的滤色片。
Description
本发明涉及用于滤色片的施主膜(donor film)，更准确地说，涉及使用热转移(thermal transfer)方法生产滤色片的施主膜。
通过颜料分散、印刷或电解积附生产在液晶显示器上获得彩色的滤色片。
所述的颜料分散方法具有加工过程中的高再现性和精确度。但是，该生产过程太长且复杂。通过所述的印刷方法，生产过程简单，但是，通过印刷方法生产的滤色片精确度差，及该滤色片不适合大型显示装置。通过所述的电解积附方法，使滤色片的平面性得到改善，但彩色特性差。
为了解决上述问题，已使用热转移方法生产所述的滤色片。所述的热转移方法是将包括转移层(fransfer layer)的施主膜布置在基片之上，然后将例如激光的光源照射到施主膜上以便转移所述的转移层到基片上的干燥方法。在热转移方法中，为了转移转移层需要许多能量，以致要求施主膜能够稳定和有效地转移。施主膜的结构通常根据被转移物质的类型、转移层的物理化学性质和能源类型而变化。
如图1所示，施主膜包括支撑层11，将吸收的光能转化成热能，形成在支撑层上的吸光层12，和形成在吸光层上的转移层13。
为完成本发明，我们已研究了施主膜的转移层和吸光层的化学组成。
本发明的目的是使用热转移方法，提供形成具有精确性和优良的彩色特性滤色片的施主膜。
为了达到本发明的上述目的，在此提供的用于滤色片的施主膜包括支撑层、吸光层和转移层，其中所述转移层包括作为粘合树脂的式(1)代表的丙烯酸树脂(acryl resin)：
其中R1为氢或甲基；
R2为C1-C12烷基、C2-C10羟基烷基、取代或未取代芳族环、C5-C10环烷基或苄基；
R3为C1-C12烷基、取代或未取代芳族环、C5-C10环烷基或苄基；
X为乙烯基、环氧基或氢原子；
0.1≤a≤0.65，0.3≤b≤0.8和0≤c≤0.2(在此a、b和c代表摩尔份数，及a、b和c之和为1)。
式(1)代表的丙烯酸树脂的玻璃化转变温度优选为30-150℃。如果丙烯酸树脂的玻璃化转变温度低于30℃，则转移层在室温下不能保持稳定，及如果玻璃化转变温度高于150℃，则需要大量转移能。
为保持在所要求水平的滤色片的耐热性、透明性和分散度，丙烯酸树脂的平均分子量优选为2×103-5×104。
根据所要求的特性，可以改变包括支撑层、吸光层和转移层的施主膜的基本结构。
例如，在吸光层和转移层之间可以形成产气层(gas producing layer)以便增加施主膜的光敏性。所述产气层包括由于从吸光层传递热能而产生气体的物质。气体的产生有助于转移层转移到接受体上。
由于热能产生气体物质之一是产生气体聚合物。该聚合物具有热分解官能团，例如叠氮基、烷基偶氮、重氮基、重氮化、diazirino、硝基、二氟氨基、二硝基氟甲基(CF(NO2)2)、氰基、硝酸基和三唑基团。
在转移层和吸光层之间也可以形成保护层。所述保护层便于转移层从吸光层分离，防止吸光层对转移层的污染。这里的保护层是由例如环氧异丁烯酸酯低聚物、氨基甲酸乙酯异丁烯酸酯低聚物、丙烯酰基异丁烯酸酯低聚物和酯异丁烯酸酯低聚物的异丁烯酸酯低聚物或所述低聚物之一和异丁烯酸酯单体的混合物使用UV-涂层(UV-coating)方法形成的。保护层也可以由使用UV-保护层方法的丙烯酸酯单体组成。
本发明的上述目的及优点通过优选实施例的详细描述并参考其附图将更加清楚，其中：
图1表示一般施主膜的结构；和
图2A和2B是图解根据本发明使用施主膜生产滤色片的视图。
根据本发明的施主膜包括支撑层、吸光层和转移层，下文将详细描述其组成。
所述的支撑层支撑其它层，并优选具有透射率为90％或90％以上。支撑层由聚酯、聚碳酸酯、聚烯烃、聚乙烯基树脂，或优选具有高透明性的聚对苯二甲酸乙二醇酯(PET)所形成。
从透明性和加工性方面考虑，支撑层的厚度优选在10-500μm的范围内。根据本发明的支撑层可形成单层或多层。也可以在支撑层上形成抗反射层以减少光的反射。
所述的吸光层形成于支撑层之上，提供能够将转移层转移到例如基片的接受体上的转移能量和由能够易吸收红外或可见光的物质所形成。这些物质包括具有0.2-3.0光密度的铝(Al)、锡(Sn)、镍(Ni)、钛(Ti)、钴(Co)、锌(Zn)、铅(Pb)及其氧化物。优选使用铝或氧化铝。使用真空蒸发方法形成厚度为50-2000的吸光层。
也可以通过在聚合物粘合树脂中分散如颜料或染料的色料和分散剂得到的分散液来形成吸光层。所述的聚合物粘合树脂是由例如丙烯酰基异丁烯酸酯低聚物、酯异丁烯酸酯低聚物、环氧异丁烯酸酯低聚物和氨基甲酸乙酯异丁烯酸酯低聚物的异丁烯酸酯低聚物所形成。所述聚合物粘合树脂也可以由所述低聚物和异丁烯酸酯单体的混合物或仅由异丁烯酸酯单体所形成。所述的颜料是由具有粒径为0.5μm或0.5μm以下的碳或石墨所形成。
优选所述吸光层具有的光密度为0.5-4.0。
对于分散剂而言，使用一般的聚合物分散剂。如果所述粘合剂同时作为分散剂，则不需要另加分散剂。
以下介绍使用通过在所述聚合物粘合剂中分散如颜料或染料的色料和分散剂得到的组合物形成吸光层的方法。
通过在例如异丁烯酸酯低聚物或异丁烯酸酯单体的粘合树脂中分散颜料和加入光引发剂可以生产光致组合物。随后，将所述的光致组合物涂在支撑层上并进行固化。通过使用挤出贴面、旋转贴面、刮刀涂布或凹槽辊涂布方法涂布所述光致组合物。此时，一般同时完成涂布和固化过程。通过上述方法形成的吸光层厚度优选为0.1-l0μm。
所述的转移层是由包括粘合树脂、交联剂、颜料、分散剂、溶剂和添加剂的组合物所形成的。所述的转移层厚度优选为0.5-2.0μm。
转移层的粘合树脂可以优选使用式(I)代表的丙烯酸树脂。
多官能单体或低聚物被用作交联剂。详细地说，所述交联剂使用多官能醇单体和/或低聚物，例如乙二醇、丙二醇、多元醇聚乙二醇和多官能丙烯酸酯单体，例如乙二醇二异丁烯酸酯、三甘醇二异丁烯酸酯、1，3-丁二醇二异丁烯酸酯，1，4-环己烷二异丁烯酸酯、三羟甲基三异丁烯酸酯，三羟甲基丙烷三异丁烯酸酯、季戊四醇三异丁烯酸酯、二季戊四醇三异丁烯酸酯。山梨糖醇三异丁烯酸酯、山梨糖醇六异丁烯酸酯和四甲基乙二醇二异丁烯酸酯。
对于所述颜料而言，使用滤光片的常用颜料。所述溶剂可以是乙酸2-乙氧基乙酯(cellosive acetate)、乙酸乙基2-乙氧基乙酯、二甘醇二甲基醚、乙苯、乙二醇二乙醚、二甲苯、环己醇、乙基2-乙氧基乙醇或乙酸丙二醇单乙醚酯。
参考图2A和2B，将描述根据本发明使用施主膜形成滤色片的过程。
将包括支撑层21、吸光层22和转移层23的施主膜25布置在基片24之上。然后将来自所述能源的能量束照射在施主膜25之上。此时，可以使用激光束、氙灯或卤素灯提供所述能源。当所选择的能源通过转移装置26并达到支撑层21时，自吸光层22放热。由于所放出的热，使转移层23转移到基片24上形成如图2B所示的滤色片层23a。
参考下列实施例详细地描述本发明，本发明不限于这些实施例。
